As I said in a comment on the bug earlier, "me too". I even used your
local.conf (with paths fixed) and it built fine for me. Whether or not
it's useful I don't know.

I'll second that. You need to figure out where your host is creeping
into OE and fix that. If it's an option you could try switching host
distros or releases, trying chroot, using another computer, or just
dig in and figure out what's going on. The .log files in the temp/
directory for nunome may be of help.
